Abstract
We present a measurement of the t t ¯ production cross section σ t t ¯ in p p ¯ collisions at s = 1.96 TeV using 5.4 fb − 1 of integrated luminosity collected with the D0 detector. We consider final states with at least two jets and two leptons ( ee , eμ , μμ ), and events with one jet for the eμ final state as well. The measured cross section is σ t t ¯ = 7.36 − 0.79 + 0.90 ( stat + syst ) pb . This result combined with the cross section measurement in the lepton + jets final state yields σ t t ¯ = 7.56 − 0.56 + 0.63 ( stat + syst ) pb , which agrees with the standard model expectation. The relative precision of 8% of this measurement is comparable to the precision of the latest theoretical calculations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
